(Beyond Pesticides, March 5, 2013) Low concentrations of silver nanoparticles can cause significant disruptions to natural ecosystems, find scientists at Duke University. This research, published in the journal PLOS ONE, provides a “real-world” look at the effects of this increasingly ubiquitous material in our environment. Although nanotechnology may have  great potential to provide critical breakthroughs in medicine and electronics, one specific material, silver nanoparticles or nanosilver, is particularly suspect in terms of human and environmental health due to its antimicrobial properties and a lack of thorough testing. Nanosilver is found in a  wide range of consumer products, including sun screen, children’s toys and pacifiers, toothpaste, and disinfectants. After the material is used, it often makes its way down our drains and into our wastewater treatment plants. Because of the material’s small size, treatment plants are unable to filter out the nanosilver. This causes them to be concentrated in the wastewater treatment plant’s sewage sludge, which is subsequently dried and marketed as a fertilizer under the innocuous label “biosolids.” Sewage sludge represents the primary pathway for nanosilver’s entry into our environment, as an estimated 60% of the average 5.6 million tons of biosolids produced each year in the U.S. are land […]

(Beyond Pesticides, March 4, 2013) Two studies released on February 28th in the journal Science detail the dramatic decline of wild pollinators and their effectiveness in producing seeds and fruit on crops in comparison to domesticated honey bees. The study conducted on the effectiveness of wild pollinators, which was led by Lucas A. Garibaldi Sc.D. of Universidad Nacional de Río Negro in Argentina, collected data at 600 test fields on all continents except Antarctica for 41 crop systems. These studies come on the heels of a possible suspension of neonicotinoid insecticides, which have been linked to Colony Collapse Disorder (CCD), by states in the European Union. In the United States action currently looks less likely, as the U.S. Environmental Protection Agency (EPA) has moved to register sulfoxaflor, which the agency has classified as “very highly toxic to bees.” These studies note that even though large active colonies of honey bees are useful for pollination, they cannot fully replace the contributions of diverse, wild insects in plant pollinations. Dr. Garbaldi’s study calls for, among other policy recommendations, “consideration of pollinator safety as it relates to pesticide application.” The first of these two studies, led by Laura A. Burkle Ph.D., was titled […]

(Beyond Pesticides, March 1, 2013) In a literature review published in Toxicology last week, researchers found that environmental and occupational pesticide exposure was strongly associated with declines in sperm count. Researchers Sheena Martenies, BS, and Melissa Perry, ScD., MHS., determined that of the 17 studies evaluated, 15 of them reported significant associations between pesticides and semen quality. The researchers counted semen quality according to concentration of sperm over an area, their motility and ability to move, as well as their shapes. Researchers targeted studies on DDT, HCH, and abamectin, grouping pyrethroids and organophosphates by class. What they found was striking: almost all the studies reported a decrease in sperm concentration; decreased motility was also reported though less frequently; while morphological changes were not strongly associated in studies””only two indicated any changes to sperm shape. These findings build on a growing body of evidence that pesticide exposure at environmental or occupational levels diminished sperm health. In addition to the U.S. findings,  studies conducted on French, New Zealander, Indian, Tunisian, and Israeli men have all found decline in sperm count. Some studies record a drop by approximately 50% between 1940 and 1990, no small amount. These results might not be surprising as […]

(Beyond Pesticides, February 28, 2013) Representative Jared Polis (D-CO) announced last Wednesday that he intends to co-sponsor a bill in Congress along with Representative Peter DeFazio (D-OR) to mandate the labeling of food containing genetically engineered (GE) ingredients in the U.S. Earlier this week, the Maryland House Health and Government Operations Committee held a public hearing on state House Bill 0903, which would set requirements for labeling and disclosure of genetically engineered ingredients in food.  Other state labeling efforts have been launched in California, Hawaii, New Mexico, Oregon, Missouri and Washington. More than 90 percent of Americans believe that foods with GE ingredients should be required to be labeled; however, Rep. Polis recognizes that it is still going to be tough to get enough votes to pass. Corporate opponents have spent tens of millions of dollars lobbying against GE labeling, and a bill introduced in the state of Colorado by Representative Jeanne Labuda (D-Denver) to label GE foods was stopped after just five hours of testimony. The House Health, Insurance and Environment Committee in Denver voted 7-2 against the bill just a day after Rep. Polis’ announcement. Despite testimony from concerned consumers, parents, and health advocates, the committee said the […]

(Beyond Pesticides, February 27, 2013) Last week a U.S. Court of Appeals found that pesticide restrictions to protect endangered salmon and steelhead proposed by the National Marine Fisheries Service (NMFS) in its Biological Opinion (BiOp) were “arbitrary and capricious,” supporting Dow AgroSciences LLC and other pesticide makers’ claims that the restrictions were based on “unsupported assumptions and conclusions.” The BiOp concluded that the pesticides chlorpyrifos, malathion and diazinon, three of the most highly toxic pesticides still in use, pose risks to salmon, steelhead and their habitat. In collaboration with NMFS, the U.S. Environmental Protection Agency (EPA) is tasked with implementation of any recommended pesticide restrictions to satisfy the mandate under Section 7 of the Endangered Species Act (ESA). However, to date, EPA has not taken any actions to implement any of the proposed measures to protect endangered salmon and steelhead, in part due to challenges from industry. Dow AgroScience LLC, Makhteshim Agan of North America, Inc., and Cheminova, Inc. USA first filed a suit in 2009 (Dow Agrosciences v. National Marine Fisheries ), challenging the NMFS’ 2008 BiOp to restrict  chlorpyrifos, malathion and diazinon as being based on numerous unsupported assumptions and conclusions, and faulty analyses. The U.S. District Court […]

(Beyond Pesticides, February 26, 2013) The world’s most commonly used synthetic insect repellent is not  as effective as it once was, according to scientists at the London School of Hygiene and Tropical Medicine. While researchers found DEET to be an effective repellent after an initial application, subsequent rounds of testing mere hours later showed mosquitoes to be unaffected by its presence. The study, published in the journal PLOS One, underlines the need to develop safe, natural, effective alternative preventions to this hazardous chemical. To perform their experiment, researchers took the mosquito species Aedes aegypti, a carrier for dengue and yellow fever, and exposed it to a human arm covered in DEET. A few hours later they repeated the experiment, but this time the mosquitoes largely ignored the presence of the chemical. To find out what caused this to occur, researchers placed electrodes on the antennas of the insects. “We were able to record the response of the receptors on the antenna to DEET, and what we found was the mosquitoes were no longer as sensitive to the chemical, so they weren’t picking it up as well,”   co-author James Logan, PhD told the BBC.  “There is something about being exposed […]

(Beyond Pesticides, February 25, 2013) Both current and future pesticide laws are under assault in several states. State-run agencies in Alaska are no longer required to solicit public comments or a review process for pesticide applications on state land due to new regulations adopted by the Alaska Department of Environmental Conservation (DEC). In Maine, the state Board of Pesticides Control is considering a proposal that weakens requirements for notification of pesticide spraying in fear of West Nile Virus (WNv) problems this summer. A state bill introduced in Hawaii to require neighbors to share specific information on pesticides being used to any abutting property owners was revised by various Hawaii statehouse committees until all notification rules in the bill were removed. Alaska The decision in Alaska, which will go into effect on March 7th, allows state agencies to spray pesticides on state land without having the application subject to public comment. The new regulation replaces the former transparent process with one that only requires agencies to develop an Integrated Pest Management Plan and submit it to the DEC. This new regulation takes away the ability for the public’s input to have an impact on proposed pesticide applications on state land. The […]

(Beyond Pesticides, February 22, 2013) The U.S. Department of Agriculture (USDA) has invited the public to submit comments concerning changes to organic standards being proposed by the National Organic Standards Board (NOSB), which will be voted on at the Board’s spring meeting on April 9-11,2013 in Portland, OR. The proposals will be open for public input until 11:59PM ET March 19, 2013. The documents under Board consideration can be found on the NOSB website along with further information on the meeting, as well as where and how to register for in-person comments or to submit written comments.

We will be updating this webpage with our perspectives on the issues, so be sure to check back as new information is added. Public participation is vital to the development of organic standards, as we are all stakeholders in ensuring a safe and sustainable food supply. The public comment process represents the best opportunity for consumers, as well as farmers and processors, to have a voice as these standards are debated and adopted by the NOSB. To read the recommendations from the various NOSB […]

(Beyond Pesticides, February 22, 2013) Scientists agree that farmland and grassland birds are on the decline worldwide, but the debate over the causes has been contentious. A study published Tuesday points to pesticide use as the single most important indicator of grassland bird declines in the U.S., raising long held concerns over wildlife impacts. Researchers in the UK and Denmark have studied why grassland birds have declined faster than birds in any other biome –many linking declines to pesticide use– but similar research had not been conducted in the U.S. Proposed causes have ranged from: larger fields, the rise of uniform crop monocultures, the loss of native and natural habitat, the increase in autumn sowing and finally, the increase to fertilizer and pesticide inputs. Authors Pierre Mineau, PhD., senior research scientist on pesticide ecotoxicology with Environment Canada, and Melanie Whiteside sought to determine to what extent grassland bird declines were linked to agrochemical use in the U.S. The results show that bird decline are, in fact, most correlated to pesticide use, rather than the intensification of crop production. Using information on agricultural intensity, pesticide use data published by the U.S. Department of Agriculture’s National Agricultural Statistics Service, as well as […]

(Beyond Pesticides, February 21, 2013) On February 6, the U.S. Environmental Protection Agency (EPA) released its preliminary volatilization assessment for the registration review of chlorpyrifos, finding that vapor phase chlorpyrifos may be emitted from treated fields at levels resulting in exposure to children and others who live, work, attend school, or otherwise spend time nearby.  In some circumstances, these bystanders may be exposed to chlorpyrifos and/or the transformation product chlorpyrifos-oxon at concentrations that could cause adverse effects. Citing uncertainties, the agency is requesting comments by March 8, 2013 on the potential risks to children and other bystanders from volatilization of chlorpyrifos from treated crops. EPA’s preliminary volatilization assessment is also in response to a petition filed by the Natural Resources Defense Council (NRDC) and the Pesticide Action Network North America (PAN) in 2007, which requested that the agency revoke all tolerances and cancel all registrations for chlorpyrifos. In a letter to NRDC and to PAN dated January 25, 2013, updating these groups on EPA’s response to their September 12, 2007 joint petition regarding chlorpyrifos, EPA stated that, “This assessment represents a significant advancement in the evaluation of pesticide risks, as it will be the first probabilistic assessment of the risks […]

(Beyond Pesticides, February 20, 2013) A new report by the United Nations Environment Programme (UNEP) and the World Health Organization (WHO) has identified endocrine disrupting chemicals as having significant health implications for the global population. According to the report, these chemicals have the capacity to interfere with tissue and organ development and function, and therefore they may alter susceptibility to different types of diseases throughout life, and represents a global threat that needs to be resolved. The report cites insufficient reporting and information on chemicals in products, materials and goods and calls for more research and collaboration. The State of the Science of Endocrine Disrupting Chemicals,   a joint study by UNEP and WHO, finds that endocrine disrupting chemicals (EDCs) are important environmental risk factors for endocrine diseases. Exposures during critical phases of development play an important role in the onset of many diseases, affecting future generations. Trends indicate an increasing burden of certain endocrine diseases across the globe, and it is clear from human studies that populations are exposed to perhaps hundreds of environmental chemicals at any one time. This UN study, which is the most comprehensive report on EDCs to date, highlights some association between exposure to EDCs […]

(Beyond Pesticides, February 19, 2013) On February 14, Beyond Pesticides joined with Earthjustice, Farmworker Justice, and a number of other environmental and farmworker organizations to submit a letter to Environmental Protection Agency (EPA) Administrator Lisa Jackson, urging for long overdue revisions to the Workers Protection Standard (WPS) of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). The letter states that, “EPA’s inaction is unacceptable given farmworkers’ persistent exposure to harmful pesticides and ineffectual enforcement of the current WPS.” This letter comes after a previous petition in 2011 stressed the need for the agency to implement stronger protections for farmworkers. This letter also comes after fears from environmental and farmworker organizations over a recent EPA handout distributed during a November 2012 Pesticide Program Dialogue Committee (PPDC) meeting that downplayed the details of a 2010 EPA document released on farmworker safety. EPA has not effectively updated WPS for almost 20 years, leaving farmworkers at risk. Farm work is demanding and dangerous physical labor. A 2008 study by a National Institute for Occupational Safety and Health (NIOSH) researcher finds that the incidence rate of pesticide poisoning is extremely high among U.S. agricultural workers. An average of 57.6 out of every 100,000 agricultural workers […]

(Beyond Pesticides, February 15, 2013) Bats around the U.S. are being decimated by White Nose Syndrome (WNS). The deadly disease was detected recently at Kentucky’s Cumberland Gap National Historic Park, according to the National Park Service. Based on laboratory testing, three bats were discovered with WNS, coming from three separate caves in the park. The cold-loving fungus thrives on hibernating bats, spreading in 2006 from a cave in New York State to 21 other states in the East and Midwest. In 19 of these states there have been confirmed cases of WNS, not including detections in four Canadian Provinces (see map).  White nose syndrome is usually transmitted bat-to-bat, although the spore can also spread through human clothing, shoes or gear. The fungus causing WNS, Geomyces destructan, is extremely lethal to hibernating bats–though posing no health threats to humans, pets, or other animals– killing 90% of bats where the fungus had persisted for a year or more, totaling 5.8 million bat deaths since 2006. There are six species of cave-dwelling bats that are susceptible to WNS, including the endangered Indiana bat. There are also three species of tree-dwelling bats in the parks, but these are less at risk for contamination as […]

(Beyond Pesticides, February 14, 2013)   Beyond Pesticides’ 31st National Pesticide Forum brings together top national scientists with local and national activists and concerned citizens to share information on the issues local communities are facing, craft solutions and catalyze networks to advance positive health and environmental policy and change.

(Beyond Pesticides, February 13, 2013) After years of scrutiny and criticism, the U.S. Environmental Protection Agency’s (EPA) Administrator Lisa P. Jackson signed amendments strengthening existing standards for human research involving pesticides submitted by third parties for consideration in EPA decisionmaking. These amendments apply to studies involving the controlled exposure of participants to pesticides, with the hope that these “tougher” new standards will decrease the number of intentional human dosing studies conducted for pesticides. Even though EPA stated in 2001 that it will not consider or rely on human studies in its regulatory decisionmaking, subsequent industry pressure resulted in EPA invoking the Common Rule (40 CFR 26 – Protection of Human Subjects) for third-party intentional dosing studies. The agency promulgated new rules and made revisions to these rules, stemming from the lawsuit and settlement by the Natural Resources Defense Council (NRDC) et al., to broaden and refine rules relating to human research involving pesticides. In 2010, EPA published the proposed rule to amend EPA’s protocol for the testing of pesticides on humans. Now finalized, the rule strengthens EPA’s 2006 rule, Protections for Subjects in Human Research. Now prohibited is testing on nursing and pregnant women, children, as well as testing on […]

(Beyond Pesticides, February 12, 2013)   Is 2013 the year colony collapse disorder (CCD) begins impacting our food supply? According to the American Bee Journal, almond growers in California may not have access to the honey bee colonies necessary to pollinate this year’s crop. “We need 1.6 million colonies, or two colonies per acre, and California has only about 500,000 colonies that can be used for that purpose. We need to bring in a million more colonies but due to the winter losses, we may not have enough bees,” says Eric Mussen, PhD,  extension apiculturist at the University of California Davis (UC Davis) Department of Entomology. The problem, Dr. Mussen explains, is due to heavy losses this winter and less populous hives overall. Some beekeepers are reporting astonishing winter losses upwards of 90 percent, and in select cases complete colony loss. Honey production in 2012 was one of the worst years in the history of the United States, Dr. Mussen notes. Less honey means less food for overwintering bees, putting increased stress on colonies attempting to fight off the spread of CCD. CCD is the name given to the precipitous decline of honey bee populations around the world beginning in […]

(Beyond Pesticides, February 11, 2013) The U.S. Environmental Protection Agency (EPA) has announced its decision to allow residues of the cancer causing insecticide endosulfan on imported Chinese teas until July 31, 2016. Its decision to provide “additional time to transition to an alternative to endosulfan” raises serious concerns of further exposure to the toxic carcinogen for farmworkers and consumers. In May 2011, EPA proposed to revoke all tolerances for endosulfan, as, “It can pose unacceptable health risks to farmworkers and wildlife and can persist in the environment.” The agency proposed transition time that would allow growers time to adopt alternatives, with the last four uses ending on July 31, 2016. For tea, EPA proposed an immediate revocation, since there is little if any endosulfan used in tea production in the U.S. However, the Chamber of Commerce of the Zhejiang International Tea Industry filed a complaint indicating that it would need five years or less to find feasible alternatives to endosulfan. It also indicated that it was unable to provide comment on the tolerance revocation ruling as the EPA did not provide proper notice to the World Trade Organization. In acknowledging this oversight, EPA will allow endosulfan residues of 24 parts […]

(Beyond Pesticides, February 8, 2013) A recent study conducted at the University of Granada, Spain and published in the Journal Environmental Research proposes a link between exposure to persistent organic pollutants (POPs) in food, air, and water and prevalence of type 2 diabetes in adults, regardless of age, gender, and body mass index. The paper concludes that people with higher concentrations of DDE, the break down product of DDT, are four times more likely to develop type 2 diabetes compared to other participants in the study. Increased rates of type 2 diabetes are also associated with exposure to beta-hexachlorocyclohexane, a break down product of the toxic chemical lindane, which in still allowed for use in agriculture and certain formulations of products used to treat lice and scabies. The study was carried out by analyzing the concentrations of specific POPs in adipose, or fat, tissue of 386 adults undergoing non-cancer-related surgery in Spain. According to one of the authors of the study, Juan Pedro Arrebola, “Human adipose tissue acts as an energy reservoir and has an important metabolic function. However, adipose tissue can store potentially harmful substances, such as POPs.”    The study found that as concentrations of POPs grows in […]

(Beyond Pesticides, February 7, 2013) Despite passing the Senate Public Affairs Committee last week after an overwhelmingly positive discussion, Senate Bill 18 to amend the New Mexico Food Act, which would require the labeling of genetically engineered (GE) food and feed,  was “deemed lost” after a majority of the Senate, in an extremely rare action, voted on the Senate Floor not to adopt the committee’s report. Under Senate rules, this stopped the bill in its tracks and cut off any further debate or public input. “Even though SB 18 is dead this year, it’s clear that New Mexicans want and deserve a label that tells them whether or not their food has been genetically engineered,” said the bill’s author Senator Peter Wirth (D-25 Santa Fe). “I greatly appreciate the Public Affairs Committee’s feedback and discussion around the issue of labeling GE food, as well as Senate Majority Leader Michael Sanchez’s leadership on this issue. GE food labels are a right New Mexican consumers deserve and, while this defeat is a setback, this discussion will continue at the state and national level.” The bill passed the Public Affairs Committee five to three with Senators Craig Brandt (R-Dist 40), Ron Griggs (R-Dist […]

(Beyond Pesticides, February 6, 2013) The U.S. Environmental Protection Agency (EPA) has proposed to register a new insecticide, sulfoxaflor, which the agency has classified as “very highly toxic” to honey bees. Despite efforts underway in Europe to protect bee populations, and continued warnings from beekeepers, EPA is poised to allow another chemical toxic to bees into the environment without proper field studies evaluating long-term effects to bee colonies and with label statements that are impractical and unenforceable. With continuing reports of bee deaths, would sulfoxaflor be yet another bee disaster waiting to happen? Take action and tell EPA not to repeat past missteps and protect pollinators from sulfoxaflor by providing a public comment to EPA.   (see below for sample comments). Last month, EPA opened the comment period for the proposed conditional registration of sulfoxaflor, a new active ingredient, whose mode of action is similar to that of neonicotinoid pesticides -it acts on the nicotinic acetylcholine receptor (nAChR) in insects. Even though it has not been classified as a neonicotinoid, it elicits similar neurological responses in honey bees, with many believing that sulfoxaflor is the new generation of neonicotinoid.  EPA has noted that sulfoxaflor is highly toxic to bees, and […]

(Beyond Pesticides, February 5, 2013) Although nanoparticles are increasingly added to a wide range of consumer products, very little is known about the potential risks these materials pose to the health of our environment. A study by the Dutch research institute Alterra looked at the effects of nanoparticles on earthworms, revealing the ability of nanomaterials to cause significant harm to the beneficial organisms. Earthworms are excellent indicators of soil health, and provide vitally important ecosystem services by aerating the soil, cycling nutrients, and increasing microbial activity. The Alterra study, led by Doctoral candidate Merel van der Ploeg, compared the health and growth of earthworms in soil containing carbon and silver nanoparticles at varying amounts with worms in regular soil. Mr. Van der Ploeg found the soil containing nanoparticles reduced reproduction, slowed growth, and increased the mortality rate of exposed earthworms. Young worms are particularly sensitive to the effects of the nanomaterial. Mr. Van der Ploeg notes, “I also found damage to the skin tissue and intestinal wall, often accompanied by damage to the underlying muscle, but even though tissue damage is usually associated with inflammation, I did not observe this in the earthworms. There seemed to be a suppression of […]

(Beyond Pesticides, February 4, 2013) U.S. Senators Pat Roberts (R-KS) and Mike Johanns (R-NE) re-introduced legislation that would reduce the review requirements for pesticides applied directly to water. Similar legislation was passed in the House of Representatives in March 2011. The previous Senate version of the bill, called the Reducing Regulatory Burdens Act of 2011, passed through the Senate Agriculture Committee but never reached the Senate floor because of a hold placed on the legislation by Senators Barbra Boxer (D-CA) and Benjamin L. Cardin (D-MD). This re-introduced legislation would reduce pesticide testing by ensuring that Clean Water Act (CWA) permits are not required for the application of pesticides. In 2009, the 6th Circuit Court of Appeals ruled in the case of the National Cotton Council et al. v. EPA that pesticides discharged into water are pollutants and required to be permitted under the CWA’s National Pollutant Discharge Elimination System (NPDES). This ruling overturned Bush administration policy that exempted pesticides from regulation under the CWA and applied the less protective standards of the Federal Insecticide Fungicide and Rodenticide Act (FIFRA). CWA uses a health-based standard known as maximum contamination levels (MCLs) to protect waterways and requires permits when chemicals are directly […]

(Beyond Pesticides, February 1, 2013) The European Commission announced yesterday its position against the use of neonicotinoid insecticides, pushing nations within the European Union (EU) to impose a two year suspension on their use. The proposal, put forward at a meeting of the Standing Committee on the Food Chain and Animal Health, would restrict the application of neonicotinoids as granules, seed-treatment or spray, on crops that are attractive to bees, particularly, sunflowers, rapeseed, corn, cotton, and cereal crops. Environmental groups say that this decision should signal the way forward for the U.S. Environmental Protection Agency (EPA) to suspend neonicotinoids in the U.S. “It’s a great thing,” said New York beekeeper Jim Doan, “I’m hoping that the EPA follows in their footsteps. While I recognize our government works differently, it says something that the European government has recognized the overwhelming data on the impact of these pesticides.” The announcement comes on the heels of research conducted by the European Food Safety Authority (EFSA) which indicated that three neonicotinoid insecticides””imidacloprid, clothianidin, and thiamethoxam, produced by Switzerland’s Syngenta and Germany’s Bayer, pose an unacceptable hazards to honey bees. In its report released January 16th, EFSA concludes that systemic contamination of neonicotinoid-treated crops, neonicotinoid […]
